Technical Field

[0001] This utility model relates to the field of cooling damper installation technology, specifically a cooling damper installation structure for a vacuum quenching furnace. Background Technology

[0002] A vacuum quenching furnace is a device that heats and holds metal materials in a vacuum environment, then rapidly cools them to achieve quenching. During the cooling process in a vacuum quenching furnace, the cooling damper plays a crucial role in controlling the flow rate and direction of the cooling gas; the rationality of its installation structure directly affects the cooling effect and the stability of the equipment.

[0003] Existing cooling dampers require manual movement to the installation position by workers, followed by manual restraint and installation by tightening bolts with a wrench. This process is time-consuming and labor-intensive, and also inconvenient for later maintenance, failing to meet usage requirements. Therefore, we propose a vacuum quenching furnace cooling damper installation structure. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an installation structure for a vacuum quenching furnace cooling damper, which has the advantage of convenient installation. It solves the problem that existing cooling dampers require workers to manually move them to the installation position, then limit them with hand force, and finally tighten bolts with a wrench to install them, resulting in a time-consuming and labor-intensive installation process that is also inconvenient for later maintenance and fails to meet usage requirements.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vacuum quenching furnace cooling damper installation structure, comprising a frame, a bracket fixedly connected to the front of the frame, a housing fixedly connected to the top of the bracket, a first motor fixedly connected to the top of the housing, a drive gear fixedly connected to the output end of the first motor, a driven gear meshing on one side of the drive gear, a take-up roller fixedly connected to the inner cavity of the driven gear, a cloth belt fixedly connected to both sides of the surface of the take-up roller, a hook fixedly connected to one side of the cloth belt, a fixed seat movably connected to the surface of the hook, a connecting frame fixedly connected to the bottom of the fixed seat, a hollow block fixedly connected to the bottom of the outer side of the bracket, a spring fixedly connected to one side of the inner cavity of the hollow block, an adjusting block fixedly connected to one side of the spring, and a pin fixedly connected to the inner cavity of the adjusting block.

[0006] Preferably, a second motor is provided on the rear side of the inner wall of the connecting frame, a fan blade is fixedly connected to the output end of the second motor, a motor is fixedly connected to the front end of the left side of the connecting frame, a lead screw is fixedly connected to the output end of the motor, a threaded cylinder is threadedly connected to the surface of the lead screw, a base plate is fixedly connected to the bottom of the threaded cylinder, and a baffle is fixedly connected to the central axis at the top of the base plate.

[0007] Preferably, the inner side of the bracket is provided with a sliding groove, and a slider is slidably connected to the inner cavity of the sliding groove, and one side of the slider is fixedly connected to the connecting frame.

[0008] Preferably, both sides of the take-up roller are movably connected to the housing via bearings, and a movable groove is provided at the bottom of the inner cavity of the housing.

[0009] Preferably, a fixing plate is fixedly connected to one side of the second motor, and one side of the fixing plate is fixedly connected to the connecting frame.

[0010] Preferably, a telescopic rod is fixedly connected to the right side of the top of the base plate, and a fixing block is fixedly connected to the top of the telescopic rod, and one side of the fixing block is fixedly connected to the connecting frame.

[0011] Compared with the prior art, this utility model provides a vacuum quenching furnace cooling damper installation structure, which has the following beneficial effects:

[0012] 1. During installation, the hook is connected to the fixed base. Then, the first motor is started by the external PLC controller. The first motor drives the drive gear to rotate, which in turn drives the driven gear to rotate. The driven gear drives the take-up roller to rotate, which in turn winds the fabric tape, thereby moving the hook. The hook moves the fixed base, which in turn moves the connecting frame upward. During the upward movement, the operator manually pulls the pin outward. When the connecting frame approaches the bracket, the position of the connecting frame is adjusted so that the slide groove and the slider are aligned. When the slider cannot move, the first motor is stopped. At this point, the pin is at the bottom of the slider. The pin is then released, and the spring push moves the adjusting block. The adjusting block moves the pin, which moves to the bottom of the slider, thus limiting the slider and preventing the connecting frame from falling during operation. This ensures stability during operation, and the installation is complete.

[0013] 2. When this utility model is working, the second motor is started by the external PLC controller, which drives the fan blades to rotate. At the same time, the motor can be started, which drives the lead screw to rotate. The lead screw drives the threaded cylinder to move, the threaded cylinder drives the base plate to move, and the base plate drives the baffle to move. The height of the baffle can be adjusted to facilitate the adjustment of the cooling gas flow rate. Attached Figure Description

Example

[0021] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this utility model provides a vacuum quenching furnace cooling damper installation structure, including a frame 1. A bracket 2 is fixedly connected to the front of the frame 1. A housing 3 is fixedly connected to the top of the bracket 2. A first motor 4 is fixedly connected to the top of the housing 3. A drive gear 5 is fixedly connected to the output end of the first motor 4. A driven gear 6 meshes with one side of the drive gear 5. A winding roller 7 is fixedly connected to the inner cavity of the driven gear 6. Fabric belts 8 are fixedly connected to both sides of the surface of the winding roller 7. A hook 9 is fixedly connected to one side of the fabric belt 8. A hook 9 is movably connected to the surface of the hook 9. The fixed base 10 has a connecting frame 11 fixedly connected to its bottom. A hollow block 12 is fixedly connected to the bottom of the outer side of the bracket 2. A spring 13 is fixedly connected to one side of the inner cavity of the hollow block 12. An adjusting block 14 is fixedly connected to one side of the spring 13. A pin 15 is fixedly connected to the inner cavity of the adjusting block 14. A sliding groove is provided on the inner side of the bracket 2. A slider is slidably connected to the inner cavity of the sliding groove. One side of the slider is fixedly connected to the connecting frame 11. Both sides of the take-up roller 7 are movably connected to the housing 3 through bearings. A movable groove is provided at the bottom of the inner cavity of the housing 3.

[0022] The specific function of this technical solution is as follows: During installation, the hook 9 is connected to the fixed base 10. Then, the first motor 4 is started through the external PLC controller. The first motor 4 drives the drive gear 5 to rotate, which in turn drives the driven gear 6 to rotate. The driven gear 6 drives the take-up roller 7 to rotate, and the take-up roller 7 takes up the fabric tape 8, thereby moving the hook 9. The hook 9 moves the fixed base 10, and the fixed base 10 causes the connecting frame 11 to rise. During the rising process, the operator manually pulls the pin 15 outward. When the connecting frame 11 approaches the bracket 2, the position of the connecting frame 11 is adjusted so that the slide and the slider can correspond. When the slider cannot move, the first motor 4 can be stopped. At this time, the pin 15 is just at the bottom of the slider. Then, the pin 15 is released, and the spring 13 pushes the adjusting block 14 to move. The adjusting block 14 moves the pin 15, so that the pin 15 moves to the bottom of the slider, thus limiting the slider and preventing the connecting frame 11 from falling during operation. This ensures stability during operation and completes the installation work. Example

[0023] Based on Embodiment 1, this utility model is as follows: Figure 1 and Figure 2As shown, a second motor 17 is provided on the rear side of the inner wall of the connecting frame 11. A fan blade 18 is fixedly connected to the output end of the second motor 17. A motor 19 is fixedly connected to the front end of the left side of the connecting frame 11. A lead screw 20 is fixedly connected to the output end of the motor 19. A threaded cylinder 21 is threadedly connected to the surface of the lead screw 20. A base plate 22 is fixedly connected to the bottom of the threaded cylinder 21. A baffle 23 is fixedly connected to the central shaft at the top of the base plate 22. A fixing plate 16 is fixedly connected to one side of the second motor 17. One side of the fixing plate 16 is fixedly connected to the connecting frame 11. A telescopic rod is fixedly connected to the right side of the top of the base plate 22. A fixing block is fixedly connected to the top of the telescopic rod. One side of the fixing block is fixedly connected to the connecting frame 11.

[0024] The specific function of this technical solution is as follows: During operation, the second motor 17 is started by the external PLC controller, which drives the fan blade 18 to rotate. At the same time, the motor 19 can be started, which drives the lead screw 20 to rotate. The lead screw 20 drives the threaded cylinder 21 to move, the threaded cylinder 21 drives the base plate 22 to move, and the base plate 22 drives the baffle 23 to move. The height of the baffle 23 can be adjusted to facilitate the adjustment of the cooling gas flow rate.

[0025] Working principle: During installation, connect hook 9 to fixed base 10, and then start the first motor 4 through the external PLC controller. The first motor 4 drives the drive gear 5 to rotate, the drive gear 5 drives the driven gear 6 to rotate, the driven gear 6 drives the take-up roller 7 to rotate, and the take-up roller 7 takes up the fabric belt 8, thereby moving hook 9. Hook 9 drives fixed base 10 to move, and fixed base 10 drives connecting frame 11 to rise. During the rising process, the operator manually pulls the pin 15 outward. When connecting frame 11 is close to bracket 2, adjust the position of connecting frame 11 so that the slide and the slider can correspond. When the slider cannot move, the first motor 4 can be stopped. At this time, pin 15 is just at the bottom of the slider. Then release pin 15, and the spring 13 pushes the adjusting block 14 to move. The adjusting block 14 drives pin 15 to move to the bottom of the slider, thus limiting the slider and preventing connecting frame 11 from falling during operation. This ensures stability during operation and completes the installation.

[0026] During operation, the second motor 17 is started by the external PLC controller, which drives the fan blade 18 to rotate. At the same time, the motor 19 can be started, which drives the lead screw 20 to rotate. The lead screw 20 drives the threaded cylinder 21 to move, the threaded cylinder 21 drives the base plate 22 to move, and the base plate 22 drives the baffle 23 to move. The height of the baffle 23 can be adjusted to facilitate the adjustment of the cooling gas flow rate.
